Never one to shy away from surprises, Prince is to announce a return to the UK, just three months after the series of guerrilla gigs in London and Manchester that sparked wild excitement in February.

Prince has scheduled four arena shows with 3rdEyeGirl – at Birmingham LG Arena on 15 May, Manchester Phones 4u Arena on 16 May, Glasgow SSE Hydro on 22 May, Leeds First Direct Arena on 23 May. Before the announcement, the Guardian heard rumours two Glasgow Hydro shows had been booked, though both Prince's publicist and the venue said they knew nothing of such plans. The fact one Hydro show has been announced suggests a second might be a possibility. Tickets for the arena shows go on sale on Friday 2 May at noon, priced from £65 plus booking fees.

The news is sure to feed speculation that he is set to be the final headliner at Glastonbury, on Saturday 28 June. His last visit spanned most of February, so it's certainly within the realms of possibility he'll stay long enough to play at the festival in Somerset. Glastonbury founder Michael Eavis, however, has said the final headliner will be "one of the biggest bands in the world at the moment". Even if the festival appearance does not happen, the gap between the Manchester and Glasgow dates suggests more shows might be scheduled.

However, given the singer's unpredictability, nothing can be assured. The shows in February – accompanied by an extensive interview in Mojo magazine – were expected to be promotion for the release of Prince's new album, Plectrum Electrum. Yet there has been no sign of the record, despite it originally having been announced more than a year ago.

Instead, since the UK shows, we have had the announcement that Prince has rejoined Warner, the label he fell out with cataclysmically nearly 20 years ago, causing him to appear with the word "Slave" daubed on his face.

In March he premiered a new song, Funknroll, on The Arsenio Hall Show, and in April he released a ballad called The Breakdown online.

Prince's shows in February received almost unanimously rave reviews. "These are performances by one of the greatest funk-rock bands ever," wrote Ben Beaumont-Thomas in the Guardian. "In the end, he balances earthly immediacy and heavenly art like no other musician."
